Chapter 3 Function Introduction
3.1 Scope
Scope mode shows voltages and currents in the power system under test by means of
waveforms. Also numerical values are shown such as phase voltages, phase currents
and frequency etc. The Scope waveform screen offers an oscilloscope style of display
of voltage and current waveforms with a fast update rate. The screen header shows
the related rms voltage/current values. Channel
L1/A
is the reference channel.
